## A Note on Thickness Type: None

When measuring auto features using a portable arm machine, the thickness type of "None" still applies the thickness value if specified. The thickness is applied to shank style measurement. When you use a shank probe for measurement, you use the cylindrical shank of the probe to measure instead of the probe tip. To do this, you need to first define sample hits. PC-DMIS can then determine the location of the supported feature (Circles, Ellipses, Slots, and Notches) using the shank.
